There will never be one “ideal” brake pad for every type of vehicle or every type of driver in every situation. Driving style, personal preferences and usage requirements of your particular vehicle are undoubtedly different from one person to the next. There really is no perfect answer, so here we subdivided the pros and cons of different types of brake pads to make an informed decision about which kind is right for your need.
Organic brake pads (also known as NAO, or “non-asbestos organic”) were developed as an alternative to asbestos pads, composed of various fibers mixed with binding resins to hold them together. Some common materials used in organic brake pads include glass, fiber, rubber, carbon and Kevlar. The materials and tools used to manufacture organic brake pads are still the least expensive today, which is why the majority (roughly 70%) of new cars sold in the US still come with them from the factory.
As the name implies, semi-metallic pads contain anywhere from 30-65% metal by weight, typically consisting of steel, iron, copper, etc. combined with friction modifiers and fillers, as well as a graphite lubricant. Semi-metallic brake pads are arguably the most versatile style available, with the slight compromise being more noise and dust. They are also longer lasting and more durable, and their metallic composition can help draw heat away from the rotor and aid in more efficient brake cooling.
The comparative new material is the ceramic brake pad. Ceramic pads are composed of a dense ceramic material (like pottery fired in a kiln) with embedded copper fibers. In use since the 1980s, ceramic pads were developed as an alternative replacement for organic and semi-metallic brake pads because at the time these types produced too much noise and dust. Ceramic pads are also generally easier on rotors than semi-metallic pads.
Brake pads are the most important safety feature on every vehicle.
